Coming into the town of Eyup I was struck by the river of women (literally, actually struck), also very conservatively dressed so I entered the river and ended up at this, the Eyup Sultan Mosque, which is the most sacred mosque in Istanbul and a major pilgrimage site.

Eyup Ensari was the standard bearer for the Prophet Mohamed (he carried the flag) and this is where he is buried. Everyone wants to be buried here. The town and surrounding hills are full of mausoleums and grave yards.
